Darren Clarke has enlisted caddie Paul Morbey as he looks to halt a woeful run of form.
The Ulsterman reached the pinnacle of his Left Handed Taylormade R11 Irons
career last summer with victory in the Open Championship at Sandwich.
But he has failed to register a single top-10 finish since then, slumping to 54 in the world rankings.
He finished in a tie for 20th with Left Handed Taylormade R11 Irons at the Volvo Golf Champions tournament in South Africa last month but subsequently missed the cut in Abu Dhabi before parting company with John Mulrooney, who was on the bag at Sandwich.
Morbey, who enjoyed huge success with former Masters champion Ian Woosnam, will team up with Clarke on a temporary basis starting with next week's Accenture Match Play Championship in Arizona. Left Handed Taylormade R11 Irons
"Darren and I go back a long way so I've known him for ages and I'm looking forward to the three-week spell," said Morbey, who now caddies for young Englishman Danny Willett.
